It looks like Liam Hemsworth is feeling a bit nostalgic this week! On Thursday, the Australian actor took to Instagram to share a funny throwback photo of himself and his fiancée, Miley Cyrus, on the set of The Last Song. "Throwing it WAY back... what a 'blur.' #TBT," he captioned the out-of-focus snap. Not only do the two look so young, but we can't get over how adorably awkward they seem. After playing love interests in the Nicholas Sparks film in 2010, the two began dating in real life and eventually got engaged in 2012. Though they broke up nearly a year later, the two resumed their relationship earlier this year and are currently in the midst of planning their wedding.
